It's fine, I have 4 aquariums downstairs and my step-dad has a sound system like tht of he's club, you cant get it to max or else your ears will blow off. The speakers them selves are over 25 inches , etc.
We never put it that loud though, but the fishes do fine when we have a party occasion or something like that. Only when people jump or are violent near the aquarium which causes it to move and shake they get scared.
